Explanation of postponement or under-change

Just now, a classmate asked me to go for a drink...... It's hard to resist hospitality, so if you come back late tonight, you may not be updated. I'll try my best. I'm sorry, but not many people watched it, but I'm still a little sorry for those students who waited for more...... If there is only one shift today, I will find an opportunity to make up for it the day after tomorrow.
